Answer:
When the person is drunk the car travels 20.1 meters more than when the person is sober. The distance traveled by car is:
Person drunk: 28.1 m
Person sober: 8 m
Explanation:
The distance traveled can be found using the following equation:
Where:
v: is the speed = 90 km/h
t: is the time
When the person is sober, the time that takes to hit the brakes is 0.320 s, so we have:
And when the person is drunk, the time is 1.00 s, hence the distance is:
The distance traveled by the car when the person is drunk compared when the person is sober is:
Therefore, when the person is drunk the car travels 20.1 meters more than when the person is sober.

Answer:
Explanation:
We are asked to calculate the force you are applying to a car. According to Newton's Second Law of Motion, force is the product of mass and acceleration. Therefore, we can use the following formula to calculate force.
The mass of the car is 2000 kilograms and the acceleration is 0.5 meters per second squared.
- m= 2000 kg
- a= 0.05 m/s²
Substitute the values into the formula.
Multiply.
Convert the units. 1 kilogram meter per second squared is equal to 1 Newton. Our answer of 100 kilogram meters per second square is equal to 100 Newtons.
You apply <u>100 Newtons</u> of force to the car.
